DNB’s new headquarter consist of three buildings with a underground story that connects the buildings together. The building to the far west is designed by Dark Architects, and the concept for the facade was to give it a heavy and solid expression. We did this by playing with different depths and by using a black granite as the facade material.

The sizes of each cassettes is 900mm x 900mm and they are made by gluing 4 mm granite to an aluminium honeycomb system. In total we have more than 6100 cassettes with more than 350 different types. If we are only counting the types there are more than 10 cassettes, we are down to only 25 different cassettes types. With these 25 different types, we cover more than 90% of the facade.   To stack all the different cassettes the way we wanted, we tagged all the cassettes on the production drawing. Since they were going to start mounting from the left of the building, we also added which container every cassette should be shipped in. This to make it more efficient on the construction site.   
Every cassettes is drawn in 3D so we were in total control of the details.
